Here are the official TeamRankings 2017 college football preseason rankings, including the TR Preseason Top 25.
Our 2017 college football preseason rankings are almost entirely data-driven. We’ve used team data from past seasons to find which descriptive statistics have correlated strongly with high end-of-season power ratings. We then used those stats to create a model that predicts a team’s power rating.
Some examples of data points used in the model include:
We assign each input factor a weight based on its demonstrated level of predictive power.
The output is a power rating that represents how many points above or below average we think a team is, with 0.0 representing a “perfectly average” team.
Once we generate initial ratings, we we then check them against the betting markets and the human polls.
If our ranking for a team seems severely out of whack with those other sources, we’ll investigate. We check to see if there’s some factor that’s not taken into account by our model, that human voters and the betting market are picking up on. In some cases, we’ll manually adjust our rating to be a bit closer to the consensus. Though only rarely will we adjust it all the way to match the consensus.
Once we’ve got our final ratings, we simply sort to get our 2017 college football preseason rankings.
It’s worth noting that these preseason ratings also drive our college football season projections — at least before the season begins. As the 2017 season progresses, the impact of these preseason ratings will gradually fade, and actual game results will play a larger role in determining our team power ratings (which continue to drive the season projections).
Top two. In our preseason rankings from 2016 were five teams clustered near the top of the rankings, with no teams head and shoulders above the crowd. This year is completely different. #1 Alabama and #2 Ohio State are well clear of the field. Ohio State is 4.0 points ahead of #3 Florida State; that’s roughly the same as the 4.1-point gap between #3 Florida and #11 LSU. In other words, there’s Alabama & Ohio State at the top, and then there’s everybody else.
In our Top 25 but not the AP’s. Three teams in the TR Preseason Top 25 did not rank in the AP’s version:
We like ’em better than the AP does. Other teams we ranked higher than the AP voters include:

Dear Hardcore Fan Of Team X,
Before you make an enraged comment about where we’ve ranked your beloved alma mater and call us a bunch of mouth-breathing Harambe haters who eat their mac and cheese with a spoon, please keep two things in mind:
